Arguably the most ruthless of Rally's adversaries, "Iron Goldie" is a high-ranking member of a Sicilian mob family. Of Italian descent, she is often referred to as a Mafia Queen. Goldie is an exceptional hand-to-hand combatant and excels at devising intricate plans. While these schemes frequently succeed, they also reveal her disregard for her subordinates.
A pathological personality, Goldie embodies the textbook definition of a "control freak." She is obsessed with dominating everything and everyone around her. Individuals who resist her, like Rally, only become more appealing to her. Goldie identifies as a lesbian, though this manifests in a sadistic manner. She maintains a harem of young girls who have committed patricide while under the influence of her drugs.
Rally and Goldie have crossed paths multiple times, with the bounty hunter narrowly escaping with her life and those of her companions. This resilience sets Rally apart from Goldie's previous adversaries, turning the mobster's admiration into a dedicated sexual obsession. Goldie resolves to make Rally her ultimate creation—a slave broken by psychological torture without the aid of chemicals.
The foundation of Goldie's power lies in psychopharmacology, particularly hallucinogenic drugs akin to LSD. Over time, she has perfected mind control techniques. Once she chemically controls someone she deems worthy, she orders them to kill their loved ones. The alternative to her induced fantasy world is a harsh reality where they have murdered those who cared for them. No one she has fully enslaved has escaped her control.
Her current empire revolves around Kerasine, a potent designer drug central to the series' plot. It can be produced cheaply, but its formula remains unreversed by external chemists. Kerasine's popularity stems from its low cost and its ability to mimic the effects of various drugs: small doses act as stimulants like cocaine, larger doses produce euphoria similar to heroin, and full vials combine both with powerful hallucinations akin to LSD.
Kerasine users can receive hypnotic commands while under its influence. Currently, it is the world's most popular drug in the manga universe. Several storylines detail Rally's efforts to prevent Goldie from flooding Chicago with this substance, including one where Rally's father, influenced by Kerasine, becomes Goldie's personal assassin.
